One reason we won't see Ogres as a playable class.

Clearly Ogres will be the next playable race for the Horde.
Rexxar will be their racial leader and will help Thrall bring the Horde back to what it was before Garrosh.
Their mounts are boars, and their is more then a concept, they have the models ready for female Ogres, we'll be seeing all this at Blizzcon.
I cannot prove my sources but lets just say it's happening.

They're too fat to fit in any gear. It'd look really silly.

And this makes them sooo different to Pandaren. Not arguing they look ridiculous, but there's your precedent.
